6 Claims.

'I'his invention relates'generally to improvements in the art ofpackaging commodities, and relates more specifically to an improveddecorative and protective wrapper for concealing or confining one ormore articles, and to an improved piackage resulting from the use ofsuch a wrap- D ng.

Generally stated, an object of the invention is to provide a simple andhighly protective wrapper for diverse articles, which will produce anattractive and compact final package.

It has heretofore been customary to wrap articles such as chocolatecoated confections, in double flexible wrappers, each comprising aninner metal foil Wrapper and'an independent outer transparent ortranslucent wrapping of the same size, surrounding and cooperating withthe inner foil wrapper to protect the article and to produce anattractive external appearance. By utilizing a tin or aluminum foilinner wrapper and an outer orange colored translucent wrapping for theinner wrapper, a glowing golden color results; and with the aid ofsuitably colored printing or other decorations applied to the outerwrapping, it is possible to produce a relatively attractive finalpackage. Because of the relatively high cost of metal foil, and of thefact that the outer and inner components of these prior wrappers wereofthe same area or size, these previous composite wrappings were rathercostly to produce, and considerable metal foil was wasted since itwasused to also cover relatively guarded rear portions of the articles suchas may be sufficiently protected merely with the aid of the cheaperouter wrapping material.

It is therefore a more specific object of the present invention toprovide a less'expensive but equally protective wrapper which possessesall of the above stated advantageous characteristics of the priorcomposite wrappers referred to.

Another specific object of the invention is to provide an improvedwrapper for articles such as chocolate` bars or chocolate coatedconfections, which will effectively protect only certain relativelyexposed portions such as the top, sides, and ends of the articlesagainst detrimental action of light, but which will totally conceal andprotect the commodity against moisture.

Still another specific object of the invention is to provide a durableand compact composite wrapping which can be readily manufactured andutilized with minimum waste of material and hence at minimum cost, andwhich constitutes a unitary covering adapted to be applied to an articlein one operation.

. A further specific object ofthe invention isv to provide an improvedpackage of highly attractive and ornamental appearance, wherein theconcealed article is most effectively protected against possibledeterioration dueto light, moisture, or other exposure.

These and other objects of the invention will be apparent from thefollowing detailed description.

A clear conception of an embodiment of the invention, and of the mode ofproducing'and of utilizing improved wrappers manufactured in accordancetherewith, may be had by referring to the drawing accompanying andforming a part of this specification, wherein like reference charactersdesignate the same parts in the several' views.

Fig. 1 ls a rear plan view of one of the improved composite wrappersshowing portions thereof folded up so as to show the details ofconstruction, and also showing fragments of adjoining wrappers indot-and-.dash lines;

Fig. 2 is a transverse section thruvthe wrappers of Fig. 1, taken alongthe line ZEE-II; and

Fig. 3 is a side elevation of a package utilizing the improved wrapper.

While the invention has been shown and described herein as beingspecically 'applied to a wrapper which is especially adapted for use inthe packaging of chocolate bars or the like, it is not intended to limitthe scope by such specific disclosure.

Referring to the drawing, the improved composite wrapper comprises ingeneral an outer sheet 5 of transparent or translucent'material; aninner or intermediate strip or sheet 6 of metallic foil adhesivelysecured along one of its edges to the inner surface of the sheet 5 asindicated by the area l; and preferably an innermost backing sheet 8attached directly to the rear surface of the inner sheet- 6.

The outer sheet 5 may be formed from a continuous ribbon of materialsuch as glassine paper, which, in the embodiment speci'callyillustrated, is orange colored and semi-transparent thruout its entirearea. This material is moisture resistant and will not stick toarticlessuch as candy bars because of its smooth and non-porous. texture. Theouter surface of the sheet 5 may, if desired, be provided with adecorative border 9 and identifying printing, to form a local window l0as shown, thru which a portion of the `underlying metal foil strip 6 ishazily, but not clearly, visible.

The metallic foil inner strip or sheet 6 is of considerably less widththan, but of the same length as'the outer sheet 5, the area of thissheet 5 being suicient to cover only the entire top,

portions of the sides, and' the entire ends of the articles which are tobe concealed in the wrapper,

as shown in Fig. 3. Such metallic foil will tear rather readily and ifbrought into direct contact with articles such as candy or chocolatebars, will vtend to stick to the article. 'I'he backing sheet 8 istherefore provided as a reenforcement for the foil and to preventsticking. As specically shown, the sheet 8 may be formed oi tough tissuepaper `and is attached directly to the rear surface of the foil sheet 8by applying a paraiiin coating or other adhesive between these elements.

`In some instances, the sheet 8 may consist of a strip of box-coverpaper, comprising a tough tissue paper coated with foil. These stripsmay, in any event, be formed Vas continuous ribbons which, as previouslyindicated, are adhesively secured to the outer sheet ribbons at linealareas 'l before the composite ribbons are severed into lengths to formthe unitary wrappers. While the inner strip 6 an'd'sheet 8 have beenshown in Fig. 2 as extending away from the outer sheet 5 at a slightangle, the outer and inner components of. the wrapper will normally beiiat against each other. .y

During the manufacturaof the improved wrappers, the composite innerstrip, comprising the foil sheet 6 andthe backing sheet 8, is hrstproduced by attaching these componentsy to each other with the aid ofparaiiin; and this parain, besides' connecting these parts, also servesto make the inner strip moisture resistant and prevents the foil fromcoming in direct contact with the article. The 'inner foil strip 6 isthen adhesively attached -along one edge and' at the area l to the innersurface of the ribbon from which the outer sheets 5 are to be formed,thus producing a continuous ribbon of the outer wrapping material havinga strip of the inner wrapping material secured to the inner surfacethereof and lying hat against this surface. The composite ribbon issubsequently severed into suitable lengths to produce the final wrapperumts in succession, and the outer surfaces of these wrappers may beprovided with decorative printing, such as the borders 8,- either beforeor after the severing operation.

Each of individual articles may subsequently be concealed within one ofthe composite wrappers thus produced in one operation by locating thewrapper so that the protective inner strip directly engages the top,portions of the opposite sides, and the ends-"of the article, and bysub- 'or glowing golden effect. The gold color results fron the use of asemi-transparent orange colored I outer sheet 5, cooperating with asilver colored shiny surfaced intermediate sheet 6. 'I'he at tachment of-the foil sheet 8 to the inner surface of theouter sheet 5 along an edgeportion only 'a layer of adhesive-between these sheets thru-out theirentire cooperating areas. 'I'he concealed article is eectively protectedagainst detrimental action bylight and moisture at those portionsthereof which are exposed during normal display of the package, and theentire article is furthermore protected against moisture and contactlwith other objects, at the bottom, by the multiple layers of the outersheet 5 alone. While the wrapper shown has been provided with a definitewindow 10, 'such window may obviously be omitted and any other form ofdecoration may beapplied to the outer surface of the hesion to thewrapped articles. The nal package Y presents a neat and highlyattractive appearance, and by limiting the area of the foil, the cost ofproducing the improved Wrapper is reduced to a minimum withoutdestroying the effectiveness thereof. The outer wrapper mayfobviusly beformed of material other than glassine paper, and other foils may beutilized in producing the sheet t; but in any case, it is desirable tohave the outer sheet formed either of transparent or semitransparen'tsheet material which is` moisture proof and relatively tough. Theuniform coloring of the outer transparent sheet 5, which may be producedin any suitable manner, may extend thru-out the entire area of thissheet or only over the intermediate sheet 6, and either the coloring ofthe outer sheet or the coloring of the foil sheet may be varied toproduce a great variety of attractive emblazoned eiects; and the readingor decorative matter may be applied to the surface of the outer sheet 5above the foil refiector, by printing or otherwise. The improved Wrapperhas proven highly successful in actualuse and may b e convenientlyhandled and applied to produce a package having minimum bulk.

It should be understood that it is not desired to limit the invention tothe exact details of construction and to the precise mode of utilizingthe Wrappers herein shown and described, for various modificationswithin the scope oi' the claims may occur to persons skilled in the art.
